<p>PURPOSE:To provide excellent offset resistance and to prevent the image deterioration by oil transfer by incorporating the toner particles directly obtd. by a suspension polymn. method into color toners and incorporating wax into these toner particles. CONSTITUTION:The color toners forming the color images fixed on both surfaces of a transfer material have the toner particles directly obtd. by the suspension polymn. method. The toner particles contain the wax. The wax is paraffinic wax and is preferably incorporated at 0.1 to 50 pts.wt. into 100 pts. wt. polymerizable monomer. The wax that contains the toner particles has 50 to 250J/9 heat quantity DELTA H for melting and the wax is preferably incorporated at 5 to 4 pts.wt. into 100 pts.wt. polymerizable monomer. As a result, the excellent offset resistance is obtd. without using oil at the time of fixing or at the small amt. of use in the case of formation of the color toner images fixed onto both surfaces of transfer paper.</p> |
